Coronavirus (COVID-19) Collection
- Olfactory and/or gustatory dysfunctions (OGD) are specific symptoms of COVID-19 (Salmon Ceron et al., 2020). Olfactory (OD) dysfunction have drawn considerable attention in the beginning of the pandemic, more than gustatory dysfunction (GD) (Klopfenstein et al., 2020; Parma et al., 2020). However, OGD's impact on quality of life seems to be majority due to GD (Coelho et al., 2021) which is defined as partial (hypogeusia) or complete (ageusia) loss of taste. Questions about COVID-19 GD remain, especially GD duration and the proportion of patients with persistent GD (Hopkins et al., 2021).
- The novel coronavirus (severe acute respiratory syndrome coronavirus 2; SARS-CoV-2), which is the cause of novel coronavirus disease 2019 (COVID-19), first reported in Wuhan, China, has spread across the world and has been characterized by the World Health Organization as a global pandemic (Bedford et al., 2020). In February 2020, at the port of Yokohama, Japan, an outbreak of COVID-19 among passengers and crew of the Diamond Princess cruise ship occurred, with approximately 700 confirmed cases.
- The novel coronavirus disease 2019 (COVID-19) outbreak has caused 6088 cases and 41 deaths in Republic of Korea, and 3144 cases and 107 death in Italy by 5 March 2020, respectively. We modelled the transmission process in the Republic of Korea and Italy with a stochastic model, and estimated the basic reproduction number R0 as 2.6 (95% CI: 2.3–2.9) or 3.2 (95% CI: 2.9–3.5) in the Republic of Korea, under the assumption that the exponential growth starting on 31 January or 5 February 2020, and 2.6 (95% CI: 2.3–2.9) or 3.3 (95% CI: 3.0–3.6) in Italy, under the assumption that the exponential growth starting on 5 February or 10 February 2020, respectively.
- The coronavirus disease 2019 (COVID-19) was first reported in Wuhan, Hubei Province, China at the end of 2019, and soon spread to the rest of China and overseas (Bogoch et al., 2020). At the time of writing, 78 630 cases had been reported in China and 3664 cases had been confirmed in 46 other countries (World Health Organization, 2020). Iran has recently become an epicenter in the Middle East region and has seen the largest cumulative number of deaths outside China (Wikipedia, 2020). As of March 1, 2020, Iran had confirmed 987 COVID-19 cases, including 54 associated deaths (Wikipedia, 2020).
